After having a hard time getting xmonad installed via my destro, I've followed the "Building using Stack" instructions online (
https://xmonad.org/INSTALL.html). The build seemed to have worked okay. However, when I try to start xmonad with my config file, I get many import errors. I've checked out the tagged versions v0.15 of xmonad and v0.16 of xmonad-contrib. Has the libraries changed at some point or is the compiled version having a hard time finding them? Is the problem in how I'm building xmonad or in my configuration?
